| Abstract: | Solid electrolyte of Li_(1.3)Al_(0.3)Ti_(1.7)(PO_4)_3 thin films were prepared by sol-gel technique.The phase identification and surface morphology were investigated by X-ray diffraction and scanning electron microscopy.Electrochemical window and electronic insulating properties were examined by cyclic voltammetry and current testing instrument.The results show that the films with good crystallinity are homogeneous,dense and crack-free.The electrochemical window is more than 2.4V,and the electronic conductivity is 10~(-11) S.cm~(-1).The film possesses wide electrochemical window and good electronic insulating. |
